PRINTING ATTACHMENT FOR' CAP-FORMING MACHINES.

Application filedAugust 23, 1921. Serial No; 494,489.

r o all whom it may concern.

Be it known that LCHAnLns A. GARRETT, a: citizen of the United States, residing in the city of. Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improved Printing Attachment for Cap-Forming Machines, of which the following is a specification.

My invention relates to mechanism for printing successive sections of a strip or sheet of material, generallyfibre paper, in

.synchronisin with the operation of means for forming caps or disks suitable for'closingbottles and containers, as such material is fed intermittently through. the coordinated printing and dieingmechanism.

A primary object of my. invention is to provide a relatively simple and efficient printing mechanism that can 'be attached and used in cooperation with known dieing,

mechanisms, for: the purpose specified.

The characteristic features of: my 1mprovements are embodied in the machlne set out in the following description and the ac-- companying drawings in illustrationthereof. .In the. drawings, Fig. 1 is:a front elevation of a .known-form-of apparatus for producingacontainer caps, in combination with the printing attachment of my invention;

Fig. .2- -is. afront elevation on an enlarged scale ofthe printing attachment illustrated in Fig.v 1; Fig. 3 is a broken sectional view taken on the line 3 -3 of Fig. 2; Fig. 4

is a broken sectional view similar to that'of Fig. with the parts in a secondposition;

Fig. 5 is a top plan view. ofa construction of the printingattachment with the head or stationary platen removed; Fig. 6 is a broken sectional view taken on the line 6 6 of Fig. 5.

.The machine illustrated comprises a cap or disk forming mechanism having a frame provided with the bed 1 and the housing 2. The crank shaft 3, journalled in the housing, is driven by the wheel 3 and operates the connecting rods 4 and 5 to reciprocate the male dieing and cutting devices 6 and 7 which cooperate with the female dieing mechanism 8 in forming the caps from a .sheetof material A fed thereto intermittently through a guide 9, the sections of the should be desired by reason of the character of: the cover to be formed.

The printing attachment illustrated com" A sprocket wheel 11, fixed on and revolved by the shaft 3, drives the sprocket chain 12 which passes over the idler sprockets 13 fixed to the sliding frame 2 and under the sprocket wheel 14 fixed on the shaft 15 which is journalled in that frame. A bevel gear 16, fixed on the shaft 15, drives a bevel gear 1'7 fixed on a shaft 18 journalled in the frame, the latter shaft having a disk 19 fixed thereto. A crank pin 20, fixed eccentrically in the disk 19, operates a rod 21 connected by a universal joint 22 with a dog 23 having a pivotal connection 24 with a slide 25 adapted to be reciprocated along the ways 26 carried by the frame 2, the slide 25 being provided with the slotted block 25' through which the sheet Ais drawn and with the recess 25 in which the serrated jaw 23 of the dog ismovable to engage and disengage the strip with reference to the block and slide; sothat in the forward latter will engage the strip to the block and carry saidstripiforward,while in the rearward movement .ofthe slide, through the action of the said parts thereon, the dog is retracted and the strip disengaged.

A dog'27 is fixed on the shaft 28 journa-lled in the frame in position to engage the stjripA to the stationary bearing27 over which it is drawn, the dog being held in frictional engagement with the strip by the actionon the arm 29 fixed .in the shaft 28 of the coiled spring 30 having one end connected to said arm and the other fixed to the fra net, the sheet'passing-between the parts 27 and 27' from the guide roller 31 journalled in the frame.

Parallel webs or tracks 32 are positioned for carrying the strip under the printing head 33, detachably fixed to the frame by the screws 34, said strip being fed forward intermittently to simultaneously position different sections thereof so that during the,

intervals of rest they'- will be first printed and the printed: sec-tionskth'en' formedby" the dieing mechanism.

The printing is effected- .by a printing form -35 carried in a frame or block 36 adapted to be oscillated on the bearings 37,'

so that the form can be engaged with the strip A in its periods of rest and press the mic against the part 33 to effect the printing operation intermittently, and so that the printing form can be withdrawn from the strip and re-inked during the step by step forward movements on the strip.

The oscillatory printing mechanism is operated through the bearing 38 on the part 36 connected by the pin 39 with a link 40 which is connected by a pin 41 with an arm 4-2 on the ring or band of the eccentric 44, the latter being fixed ecccntrically on and revolved by the shaft 15. An arm 1-5 fixed on the part 36 carries a roller 1:6 which acts in the curved way 1-? of an arm t8, the latter being fixed on a shaft it) journalled in the frame. Arms fixed to the shaft 4-9 are connected by pins 51 with links 52 engaged by the pins 53 to respective arms 54 adapted to rock on the shaft 15. An ink roller 55 has its end pintles journalled in slide bearings 55 engaged in the bifurcated ends 54 of the arms 54, the rollers being drawn inwardly by coiled springs 56 connected with the arms and slide bearings. The roller runs upon and its movement is controlled by guide bars 47 fixed to the frame, the guide ways being so formed and the mechanism so timed that in the lowered inclined position of the oscillatory part 36 the roller will move over the type or printing form and ink the same, and in the upward movement of the part 36 the roller will be withdrawn therefrom to efiect reinking in engagement with the roller 58.

An ink font 59 supplies ink to the roller 58, the latter being revolved in the ink through the connection of the sprocket wheel (30 thereon by a sprocket chain 61 with a sprocket wheel 62 fixed on the shaft 15.

It will now be understood that the rota tion of the shaft is transmitted through the sprocket chain 12 to the shaft 15 and therethrough and through shaft 13, disk 19, and 'o l 21 to rock the dog 23 and cause it to grip and advance the sheet A under the roller "1, dog 27, between guides 32 and platen r') E t irough the guide 9 and under the dies (3 and 7 which are meanwhile being elevated by the connecting rods 4 and 5. In synchronisin with this forward movement of the sheet A, the bed 36 is lowered by the :wiliml of the eccentric and through the arm 45 rocks the crank 4-8, shaft 49, crank 51 and link 52 to oscillate the arms 54 and cause the roller to move over and ink the f: i 235, the roller having been inked by contact with and revolution by the inking roller 58 driven from the shaft 15.

iVhen the slide 25 carrying the dog 23 has reached its forward limit of movement and begins its rearward movement, the pull of the link 21 retracts the toothed part 23 from the sheet A, which is held stationary by the dog 27. While the sheet is thus held motionless, the bed i6 is elevated thereby moving the roller 55 back to the roller 58 and 1mprinting the desired impression on the sheet, which is maintained by the guides 32 against the platen 33. The synchronized descent of the dies 6 and 7 cuts from the printed sheet the desired caps or closures. To secure perfect registration of the cutting dies relatively to the impression, the slide 2 is adjusted by means of the screw 1" and lugs 2.

Having described my invention, I claim:

1.
